… Then, we derive the exact OPs and ECs for imperfect SIC in Sections III and IV, respectively.
In Section V, we provide the asymptotic OPs and ECs for high-SNR regimes. The feasibility …

… Abstract—This paper presents a non-orthogonal multiple access (NOMA)-based spectrum
sharing scheme with imperfect successive interference cancellation (i-SIC), where the …

… system was studied with imperfect successive interference cancellation (SIC) to highlight …
spectrum sharing mode and such Hetnet implements in two-tier. It was shown that the spectral …

… Therefore, the shortage of spectrum resources becomes increasingly prominent [15]. CR
allows the SU to use the licensed spectrum to realize spectrum sharing so that spectrum …

… pilot contamination and imperfect SIC. We also observe that, imperfect SIC degrades NOMA;
… However, this also increases the interference due to pilot contamination and imperfect SIC …

… scheme under imperfect CSI and SIC. Specifically, we focus on spectral efficiency maximization
… of smart spectrum sharing, where a portion of the spectrum allocated to one user can be …

… = 0.1, respectively, while the OP for perfect SIC is 5.3 × 10 … Here, we notice that the
imperfect SIC of э = 0.01 degrades the OP for 10 times and the increase of the SIC imperfection …

… on imperfect successive interference cancellation (SIC) at the … of imperfect SIC. Simulation
results verify our analytical results. … Moreover, we also consider impact of the imperfect SIC to …

… In this work, we have adopted an overlay spectrum sharing paradigm for information
transmission (IT). Further, the CR network with cooperative relaying can increase the network …
